You don’t need to log in the user to view products. The authentication call basically authenticates your app, and gives you back a token to use in subsequent calls to the API. Each token lasts for an hour and if you use something like our Javascript SDK it will handle refreshing the token for you.

Hey @handre you don’t have to use the SDK, but it makes it a lot easier to handle authentication.

If you don’t want to use the SDK you will need to handle the authentication in your code. You could have a look at the source code of our SDK to see how this handled and implement it in your own solution.
